Relationship of Hypochaeris salzmanniana (Asteraceae, Lactuceae), an endangered species of the Iberian Peninsula, to H. radicata and H. glabra and biogeographical implications
(Wiley-Blackwell, 2004)
Hypochaeris salzmanniana DC. (Asteraceae, Lactuceae) is an endangered species on the Iberian Peninsula, known from only eight coastal populations. Most authors have treated it as a variety, subspecies or simply as a synonym ...

On the existence and multiplicity of positive solutions for some indefinite nonlinear eigenvalue problem
(American Mathematical Society, 2004-06)
This paper concerns with the existence, uniqueness and/or multiplicity, and stability of positive solutions of an indefinite weight elliptic problem with concave or convex nonlinearity. We use mainly bifurcation method to ...

P Systems with Tables of Rules
(Fénix Editora, 2004)
In the last time, several e®orts were made in order to remove the polarization of membranes from P systems with active membranes; the present paper is a contribution in this respect. In order to compensate the loss of ...

Study of the stabilization energies of halide-water clusters: An application of first-principles interaction potentials based on a polarizable and flexible model
(American Institute of Physics (AIP), 2004)
The aim of this work is to compute the stabilization energy Estab(n) of [ X(H2O)n ]- (X=F, Br, and I for n=1 – 60) clusters from Monte Carlo simulations using first-principles ab initio potentials. Stabilization energy of ...

On the controllability of the heat equation with nonlinear boundary Fourier conditions
(Elsevier, 2004-01-20)
In this paper we analyze the approximate and null controllability of the classical heat equation with nonlinear boundary conditions of the form ∂y ∂n + f(y) = 0 and distributed controls, with support in a small set. We ...

Securin Is a Target of the UV Response Pathway in Mammalian Cells
(2004)
All eukaryotic cells possess elaborate mechanisms to protect genome integrity and ensure survival after DNA damage, ceasing proliferation and granting time for DNA repair. Securin is an inhibitory protein that is bound to ...

A(e’,e’)B responses: From bare nucleons to complex nuclei
(American Physical Society, 2004-10-01)
We study the occurrence of factorization in polarized and unpolarized observables in coincidence quasielas-tic electron scattering. Starting with the relativistic distorted wave impulse approximation, we reformulate ...

Looking for P Truth
(Fénix Editora, 2004)
In a general sense, Logic studies how to derive new pieces of in- formation from previous ones. In this paper we explore the analogies between P systems, where new configurations can be obtained from previous ones by using ...

Tissue P Systems with Cell Division
(Fénix Editora, 2004)
In tissue P systems several cells (elementary membranes) commu- nicate through symport/antiport rules, thus carrying out a computation. We add to such systems the basic feature of (cell) P systems with active membranes { ...
